Peptides, Z-Val-X-Gly-OMe, containing a very bulky α,α-disubstituted glycine, such as N-benzyl-α,α-diisopropylglycine or N-benzyl-α,α-diphenylglycine, as the residue X can be synthesized in moderate yields by four-component condensation (Ugi reaction) at high pressure (9 kbar, 0.9 GPa).
含有非常庞大的α,α-二取代甘氨酸(例如N-苄基-α,α-二异丙基甘氨酸或N-苄基-α,α-二苯基甘氨酸)的肽Z-Val-X-Gly-OMe,其残基X可以在高压(9 kbar,0.9 GPa)下通过四组分缩合(Ugi反应)以中等收率合成。
